掃している。Since the DC high pressure generator is stopped at that time, the electrostatic precipitator is in an uncharged state during the cleaning operation. The cleaning method inside the electrostatic precipitator is such that a discharge electrode hammering device and a dust collection pole hammering device hammer the discharge electrode and the dust collection pole, respectively.
The dust adhering to the discharge electrode and dust collecting electrode is scattered and dropped, and the discharge device carries it out of the electrostatic precipitator to clean the inside of the electrostatic precipitator.

った。However, during the cleaning operation of a conventional electrostatic precipitator,
Dust that has adhered to or accumulated on the dust collection electrode or discharge electrode can be hit with a hammer using a hammering device to cause it to scatter and fall, but it is not possible to cause the dust that has adhered or accumulated to the inner wall of the dust collection chamber to scatter and fall. The dust adhering to and accumulating on the inner walls of the dust collecting chamber is scattered and fallen by the influence of the ionic wind caused by the blow-up when the gas blow suddenly changes and the sudden increase in the output current during re-discharge. This scattered and fallen dust scatters to the gas outlet of the electrostatic precipitator and is discharged from the gas outlet when normal operation is restarted, which may increase the outlet dust concentration.
本発明はこのような事情に鑑みて成されたもので電気集

Features.
本発明によれば、先ず、集塵室のガス通路の出口若しく
は出入口が閉鎮される。集塵室から碍子室へのガス侵入
を防止させる為、碍子シールファンを連続作動させる。According to the present invention, first, the outlet or entrance of the gas passage of the dust collection chamber is closed. The insulator seal fan is operated continuously to prevent gas from entering the insulator room from the dust collection room.

ようになる。Furthermore, the DC high pressure generator is configured to repeat activation and deactivation multiple times. At this time, the current generated from the DC high voltage generator is set to maximum output. When the DC high-pressure generator is activated to generate charge on the discharge electrode, an ion wind is generated in the dust collection chamber due to the instantaneous charge. The ion wind can be obtained multiple times by alternately repeating the activation and stopping of the DC high pressure generator multiple times. Due to the ion wind, dust that cannot be scattered and fallen by simply hammering the discharge electrode and dust collecting electrode with a hammering device, dust that has adhered to or accumulated on the inner wall surface of the dust collection chamber, etc., and the hammering device can hammer the dust. The scattered and fallen dust newly adheres to the inner wall surface of the dust collecting chamber, and the accumulated dust is scattered and fallen during the cleaning operation, and is carried out by the discharge device.
